Title: Photographic apparatus
IPC: G03B19/18
Filed: 1973-06-04
Abstract: 1412859 Cinematographic apparatus POLAROID CORP 4 June 1973 [9 June 1972] 26470/73 Heading G2E  Photographic apparatus e.g. a projector, for use with a film cassette, comprises a latch 73 for releasably retaining the cassette in the apparatus, an ejector 25 for ejecting the cassette, a control system 99 for controlling the performance of a predetermined sequence of operations including moving a film within a cassette latched in the apparatus and actuating the ejector at the completion of the sequence, and a manual over-ride control which, when actuated, interrupts the sequence to permit actuation of the ejector at any time during the sequence. Insertion of a cassette 1 into a pocket 2 in the projector depresses a pedal 25 pivoting it about 131 against the action of a spring 132 (Fig.8). This movement disengages a yoke 129 connected to the pedal 25 from a pin 73, so that the pin is forced into a hole in the cassette under the influence of a spring 125, thus holding the cassette in the pocket 2. After the pin 73 has entered the cassette a collar 127 on the pin 73 holds the yoke 129 down, thus latching the pedal 25 down against spring. 132. The control system 99 includes logic gates which control the operation of solenoids SL1-SL5, which determine the movement of sprockets 77, 78 and 142, blinds 151 and 153 and pin 73; and motors TM and SM which drive the take-up and supply reels respectively. After insertion of the cassette sprockets 77 and 78 are moved into contact with sprockets on the supply and take-up reels. Two blinds 151 and 153 are moved to expose a projection aperture 64 in the projector and an aperture 14 in the cassette which admits light from a lamp K. Sprocket 142 is moved into engagement with a cassette snubber roller and the film is fed intermittently for projection by a pawl mechanism engaging perforations in the film, the take-up reel being driven via a slip clutch. For rewind the snubber sprocket 142 is withdrawn, allowing the snubber roller to idle, blinds 151 and 153 obscure apertures 14 and 64, the pawl mechanism does not operate, the supply wheel being driven to wind the film. If on insertion into the projector it is detected that the film in the cassette has not yet been developed the film is automatically run through and processed prior to projection. At the end of rewind sprockets 77 and 78 are withdrawn, and solenoid SL4 is briefly energized to withdraw the retaining pin 73 from the cassette. This also releases yoke 129 and enables pedal 25 to pivot under the influence of spring 132 to eject the cassette. At any stage in the above described sequence depression of a manual over-ride EPB terminates drive, retracts any sprockets engaged with the cassette, closes the blinds and ejects the cassette as described.

Title: Improvements in or relating to cinematograph or television cameras
Inventor: LANGLEY EDITH JESSIE
IPC: G03B7/085
Filed: 1954-09-14
Abstract: 779,945. Electric control systems. WESTMINSTER FILMS, Ltd. Sept. 9, 1955 [Sept. 14, 1954], No. 26620/54. Class 40 (1). [Also in Group XL (b)] The aperture of a cinematograph or television camera is adjusted in accordance with the intensity incident on a light-sensitive cell forming part of a balanced circuit, the unbalance of which is used to adjust the aperture and to rebalance the circuit. As shown, part of the output developed by cell 1 across potentiometer 2 is topped by a slider 2a, compared with that developed at a pre-set slider 3a on a further potentiometer 3, and used to operate a polarized relay 4 energizing one of two relays 15 or 16 in accordance with the direction of unbalance. According to which relay is energized motor 10 runs in one direction or the other to reposition the slider of potentiometer 2a, to recentralize relay 7 and to adjust the shutter 11a. When one of relays 15 or 16 is energized relay 20 is also energized and adds its effect to that of relay 4. Closure of one of relays 15, 16 also de-energizes relay 18 which after an interval determined by condenser 19 allows its contact to open, de-energizing relay 20. If the unbalance has meanwhile been sufficiently reduced so that relay 4 is no longer able alone to hold its contacts energized, relay 15 or 16, as the case may be, de-energizes and motor 10 stops; if not, relay 18 or 16 de-energizes because of the opening of the contact of relay 18 although relay 4 holds contact 7 closed and restores the circuit of relay 18 which then again closes its contacts supplying relay 15 and 16 and the motor again runs. Thus the adjustment of the potentiometer slider and the aperture continues in a step-by-step fashion until relay 4 allows contacts 7 to open.
